[0002] In the manufacturing and maintenance process of hydraulic equipment, the fixation of hydraulic multi-stage cylinder is a key link. During the processing of welding coils, the welding angle of the hydraulic cylinder needs to be adjusted due to the needs of the welding points to achieve the best welding effect.

[0003] When welding a hydraulic multi-stage cylinder, the hydraulic multi-stage cylinder is usually fixed on a platform. Since the hydraulic multi-stage cylinder is usually cylindrical, when welding the hydraulic multi-stage cylinder, welding is usually performed around the hydraulic multi-stage cylinder. The hydraulic multi-stage cylinder needs to be rotated frequently so that welding can be performed around the welding gun. Therefore, frequent pauses are required during welding, which will affect the quality of the welded joint, thereby prolonging the welding time and reducing the welding efficiency.

[0004] In order to solve the above problems, a hydraulic multi-stage cylinder welding fixing frame is proposed in the present application. Utility Model Content

[0015] By arranging the mounting plate, the fixed housing, the second motor, the rotating shaft and the rotating disk, the second motor is limitedly fixed by the fixed housing, so that the second motor drives the rotating disk to rotate under the connection of the rotating shaft.

[0016] Preferably, a third motor is fixedly connected to the inside of the rotating disk, a threaded rod is fixedly connected to the output end of the third motor, an outer wall of the threaded rod is threadedly connected to a limiting block, an end of the limiting block away from the rotating disk is fixedly connected to a movable plate, the top of the movable plate is rotatably connected to a welding gun, and the top of the welding gun is threadedly connected to a fixing bolt.
